Who's altering display? (4)

Ross

I believe the answer is:

show

'display?' is the definition.
(I know that display can be written as show)

'who's altering' is the wordplay.
'altering' is an anagram indicator.
'whos' is an anagram of 'SHOW'.

(Other definitions for show that I've seen before include "Expose" , "charade" , "Exhibit - present" , "Labour's evidence for starting" , "Demonstrate - parade" .)
